Innovative fabricator Whiteline and long-standing installer partner Window Wise (Sussex) have worked together to deliver a glazing solution for a prestigious commercial project. Private preparatory school Cumnor House Sussex has developed an exciting new, £3 million STEM (Science, Technology, Engineering & Maths) building on its site in Danehill, near the Ashdown Forest, East Sussex.


The school’s ethos of ‘Aim high, be kind and dare to be different’ sets exacting challenges for the design, specification and detailing of the new block. The external design is eye catching and contemporary in its setting.  Internally it contains three science labs, 3 classrooms and a Design & Technology suite that embrace innovative modern teaching methods. The school’s strong environmental principles are reflected in the incorporation of sustainable technology in the structure, including Solar PV panels, air source heat pumps, rainwater harvesting and energy efficient glazing. Interestingly, elements of each system are visually exposed, to become practical, educational tools for the school’s pupils.

The STEM block’s extensive glazing scheme maximises natural light and passive ventilation, whilst its scale and transparency softens the mass of the building. Faceted sections are important to the building’s design, projecting and complementing the curvilinear form of its striking façade. The installation consists of Whiteline manufactured ALUK aluminium frames in architectural grey (RAL7016), with 37 flat contemporary sash casement windows and 15 doors sets, all with slim-line aesthetics and expertly fitted by Window Wise. This easily maintained, resilient and durable glazing solution is well suited to the years of demanding use that the school’s energetic pupils will undoubtedly subject it to.

Cumnor House Sussex is proud of its exceptional and dynamic new facility, brought to fruition by a team of professionals featuring George Baxter Associates (Project Architects), Gould & Company (Contract Administrator) and Luke & Luke Construction, in tandem with Window Wise and Whiteline who have extended their collaboration into another successful commercial installation.
